Ever got a “ORA-01841: (full) year must be between -4713 and +9999, and not be 0” Error when trying to edit an existing user in APEX Administration Panel (Manage Workspaces > Manage Developers and Users) ?
The reason to this error can be a too large value in Manage Instance > Security > Account Password Lifetime (days). For example you can store there a number of 999999 days which is saved without any problems, but when trying to edit an user you get the ORA-01841 error message.
This error occurs in APEX 4.0.2.*, reported as Bug in APEX Forum.
Thanks Pascal for showing this error to me.
